今日きょうあって明日あすない身み

expression

life is transient; life is uncertain; memento mori

A set phrase expressing the impermanence of life, often used in reflective or literary contexts. It conveys that one may be here today but gone tomorrow.

• 今日きょうあって明日あすない身みだから、一いち日にち一いち日にちを大たい切せつに生いきたい。

  Since life is uncertain, I want to live each day with care.

expression

one's days are numbered; one's time is nigh

Used when someone's death is imminent or expected soon, often with a somber or fatalistic tone. More concrete than the general transience sense.

• 医い者しゃからはっきりとは言いわれなかったが、どうやら今日きょうあって明日あすない身みらしい。

  The doctor didn't say it outright, but it seems my days are numbered.
